According to SMM data, China's EMM production in April 2025 decreased by approximately 2% MoM and increased by over 5% YoY. Although EMM plants in Guangxi and Guizhou, which had suspended production earlier, resumed operations in April, leading to an increase in production. However, EMM plants in Hunan and other regions experienced a slight decline in production due to a shortage of manganese ore raw materials and equipment maintenance. Overall, the decrease in production in some regions offset the increase in others, resulting in an overall decline in total EMM production in April.
Entering May, the overall operating rate of manganese plants remained at 70% of their capacity. With the completion of equipment maintenance at some EMM plants, production is expected to increase slightly. Coupled with the increase in the number of calendar days in May, the overall supply of EMM is expected to increase. According to the production schedule survey of manganese plants, production on the supply side is expected to increase in May.
